The Lessons tool allows instructors to organize resources, media, and activities that are housed in other tools in the course site or elsewhere on the web. By creating direct links to these items on one or more lessons pages, instructors can simplify the navigation of their courses for their students, and also exercise more control over when and how students access course content.  

Unlike most other tools, multiple instances of the Lessons tool may be added to a single course site, meaning that instructors may organize all of their items on a single lessons page or create separate pages for individual units, topics, or course meetings.

Note: For instructions on how to add this or any other tool to your site, see How do I add tools to my site?
